where do commas go in the following passage? Last summer one of my brothers Hugo got a job as a secretary at a fire academy. This academy trains over 4000 firefighters a year. Each day during

lunch Hugo would watch training exercises. Instructors and cadets would set large structures on fire and then they would use different substances to put out the flames. Once they set fire to 10,000 gallons of liquid petroleum gas which was pretty scary. The academy also had equipment that would simulate burning buildings oil fields and ships. At the end of the summer as a going away present one of the chiefs let Hugo drive a fire truck.
